Description of ESC
Optimum driving safety now has a name : ESC, the Electronic Stability Program.
ESC recognizes critical driving conditions, such as panic
reactions in dangerous situations, a ...
Troubleshooting
Failure Diagnosis
1.
In principle, ESC and TCS controls are prohibited in case of ABS failure.
2.
When ESC or TCS fails, only the failed system control is prohibited.
3.
However, when the ...

Description
1.
The ambient temperature sensor is located at the front of the
condenser and detects ambient air temperature. It is a negative type
thermistor; resistance will increase with lower temperature, and
decrease with higher temperatures.

Inspection
1.
Turn the ignition switch OFF.
2.
Remove the ECTS (Refer to "Removal").
3.
After immersing the thermistor of the sensor into engine coolant, measure resistance between the ECTS terminals 3 and 4.
